HEEZ Research Review: Lab-Verified Lot COAs, Strict Buyer Checks, Final Sales

HEEZ Research is a US online store selling freeze-dried research peptides in sealed glass vials. It describes itself as a chemical supplier rather than a pharmacy and limits sales to buyers who say they are qualified researchers. A mailing address in Fort Lauderdale, Florida, appears on its refund page, but no legal entity name or founding year is given.

We looked at the homepage, the shop, the BPC-157 product page, the COA page and one full certificate, plus the shipping, refund and terms pages. The paperwork is stronger than most, while the refund terms are among the strictest.

What HEEZ Research sells

The shop lists 28 items. Most are single peptides such as BPC-157, TB-500, MOTS-c, SS-31, KPV, Selank, Semax, DSIP and Ipamorelin, along with blends sold as GLOW, KLOW and a BPC-157 and TB-500 blend. GLP-1 class compounds appear under coded names, and a lab water product is sold too.

Starting prices run from about $45 to $145 per listing. Vial sizes are chosen on product pages; the BPC-157 page offers 5 mg and 10 mg vials. A monthly auto-ship option is also offered. One small error stood out: the 5 mg BPC-157 description lists a 10 mg quantity.

Lot certificates from Access Analytical, with verification links

The COA page lists every current lot with its size, lot number, HPLC purity figure, test date and issuing lab. Current lots were tested in October 2026 by Access Analytical, a lab in Irmo, South Carolina. Each entry links to a PDF and to a verification page on the lab's own site. Earlier lots tested by Freedom Diagnostics and Chromate are listed as well, but without PDFs. Buyers can also look up reports by order number.

The BPC-157 10 mg certificate for lot HZ-1008-BPC10-01 shows:

• Purity of 99.69% by reversed-phase HPLC.
• Net content of 10.02 mg against a 10 mg label claim.
• Identity by HPLC retention time matched to a reference standard.
• Endotoxin, heavy metal, sterility and fentanyl screens, all passing.

The gap is identity. No mass spec result appears, so there is no observed mass to compare with the expected value. Current-lot purity figures on the COA page range from about 99.1% to 99.97%.

Research-use labeling and buyer checks

Research-use notices appear on product pages, in the footer and in the terms, and product descriptions frame each compound as an assay reference material. No usage instructions or health claims were seen.

Buyer checks are strict. Checkout asks for an institutional email that matches the ordering organization. The terms require buyers to be 21 or older, collect a date of birth and require a signed Material Transfer Agreement with each order. The store may ask for proof of lab affiliation and cancels orders that are not verified within five business days.

Shipping, payment and refunds

Orders ship from the US by FedEx 2Day or Overnight, and the terms add UPS and limit delivery to the continental US. Orders placed before noon Eastern on weekdays usually ship the same day, and nothing ships on weekends. The shipping page gives a two to four business day estimate, calculates rates at checkout and emails tracking at dispatch. Cold packs are not mentioned.

The terms list cards, ACH or wire transfer, and cryptocurrency (BTC, ETH and USDT) as payment options.

The refund page states that all sales are final, whether a vial is opened or not, and it does not describe how damaged, lost or wrong items are handled. The terms allow refunds only for verified manufacturing defects. Support is by email and phone.

Verdict: who HEEZ Research suits

HEEZ Research suits US labs that value lot-matched reports from a named lab they can check directly and that are comfortable with formal purchase paperwork. It is a weaker fit for labs that need mass spec identity data or flexible refund terms.

Before ordering:

• Match the lot number on your vial to its certificate and use the lab's verification link.
• Ask whether mass spec identity testing is available for your lot.
• Ask support how damaged or lost parcels are handled, since the policy is silent.
